The Philips 130% “Extreme Vision” H7s (dipped) seem to last roughly 2 and a half years for me and the H1 mains about 6 months longer in my Duster. Worth ever penny and the 5 minutes of swearing to fit as most of my night driving is on unlit rural roads with, lined by trees. October to April is brown season where it telling the muddy tarmac from muddy verges can be a challenge with decent headlight. The Osram OEMs were terrible.
As you’d have to be feeling generous to call my local minor roads “B” roads and I live off of what’s basically a tarmac over gravel farm track, folks living near better roads might get more life out of them.
I notice they’re 150% now as I just ordered a replacement pairs of H7s after noticing one had failed last night.
